Mike,
Your suggestion seems related to LUCENE-6229
<https://issues.apache.org/jira/browse/LUCENE-6229>. My understanding is
that we shouldn't rely on Scorer.getChildren() as you won't always get all
child scorers (just the minimum needed to match) and their positions aren't
necessarily reliable.
Should we be suggesting an different approach to Todd's question?
